The polling conducted by the New York Times and the Kaiser Family Foundation between April 8 - 15 finds the two-term incumbent with a 46-36 lead over Cotton, R-Dardanelle, among 857 registered voters surveyed.
"Arkansans are paying attention and they appreciate Mark Pryor, they trust Mark Pryor and they like having a senator that listens to them," Pryor spokesperson Erik Dorey says. "At the same time, they're skeptical and troubled by congressman Cotton's votes in Congress against Arkansas seniors, students, farmers and women."
The poll has a plus or minus margin of error of 4 percentage points.
Every other poll conducted in what's expected to be the most expensive in Arkansas history, has found Cotton and Pryor tied or separated by a close enough margin to be considered too close to call.
"We anticipate winning a hard-fought race this November," Cotton spokesperson David Ray says. "Arkansas voters are looking for a candidate who won't rubber-stamp President Obama's agenda of higher taxes, runaway spending, and Obamacare 95 percent of the time like Senator Pryor has done."
